RCD’s AT and PT Series resistors offer inherent wirewound
reliability and precision performance in all types of temperature
sensing or compensating circuits. Sensors are wound with
various alloys to achieve wide range of temperature sensitivity.
ATS SERIES 350°C RATING
ATB SERIES 175°C RATING
RCD ATS Series offer precision wirewound resistor performance
at economical pricing. Ceramic core and silicone coating
provide high operating temperature. The coating ensures
maximum protection from environmental and mechanical
damage (envir.
performance per
MIL-PRF-26).
RCD ATB Series are typically multi-layer bobbin-wound enabling
higher resistance values. Encapsulated in moisture-proof epoxy,
Series ATB meets the environmental requirements of MIL-R-93.
Operating temperature range is -55°C to +175°C. Standard
tolerances are
±0.1%, ±0.25%,
±0.5%, ±1%.

In order to determine the
available resistance range
for each TC, use the
multiplier times the 4500
ppm resistance range.
Example: a resistor with a
TC of +3200 ppm can be
manufactured with a
resistance value twice as
high as the same resistor
with a TC of 4500 ppm.
A resistor with a TC of
+6000 ppm can only reach
a third of the resistance
value available with 4500
ppm wire.
